ExtJs Ajax download 문제

Question

아래와 같이 ExtJs Ajax로 다운로드를 시도합니다.function btnStartDownload2() { var loadlist &#61; []; shadowStore2.each(function(rec){ loadlist.push(rec.get('fileName')); }); enabledDownloadStart2Btn(false); setTimeout(function(){ enabledDownloadStart2Btn(true); }, WAIT_OK_BUTTON_ACTIVE); Ext.Ajax.request({ scope : this, noCache: false, // to remove param &#34;_dc&#34; url : setIdIntoUrl_zipFilenames, form : Ext.get('app-upload-form'), binary: true, timeout : REQUEST_TIMEOUT, method: 'POST', headers: { 'Content-Type': 'application/json' }, params: JSON.stringify({ modusSelectAll: modusSelectAll2, loadFilenames: loadlist }), success : onSubmitSuccess, failure : onSubmitFailure }); }; function onSubmitSuccess(response, opts) { var disposition &#61; response.getResponseHeader('Content-Disposition'); var filename &#61; disposition.slice(disposition.indexOf(&#34;&#61;&#34;)&#43;1,disposition.length); filename &#61; filename.replace(&#34;UTF-8''&#34;, &#34;&#34;); var blob &#61; new Blob([response.responseBytes], { type: 'application/octet-binary' }); if (typeof window.navigator.msSaveBlob !&#61;&#61; 'undefined') { // IE workaround for &#34;HTML7007: One or more blob URLs were revoked by closing the blob // for which they were created These URLs will no longer resolve as the data backing the URL has been freed.&#34; window.navigator.msSaveBlob(blob, filename); } else { var URL &#61; window.URL || window.webkitURL; var downloadUrl &#61; URL.createObjectURL(blob); if (filename) { // use HTML5 a[download] attribute to specify filename var a &#61; document.createElement(&#34;a&#34;); // safari doesn't support this yet a.href &#61; downloadUrl; a.download &#61; filename; document.body.appendChild(a); a.click(); } setTimeout(function () { URL.revokeObjectURL(downloadUrl); document.body.removeChild(a); }, 1000); // cleanup } };문제는 위 방식으로 1기가 이상의 파일을 받게 될 경우, 중간에 크롬에서 크래쉬가 발생합니다.그나마 크롬 developer tool에서는 봤을 때에는, 일정용량 다운로드 되다가 문제가 발생하지만파이어폭스나 익스에서는 진행조차 되지 않는 듯 싶어 보입니다.어디가 문제인걸까요?참고로 : 서버단은 WildFly 8.2.1 &#43; Java Webservice로 구성되어 있습니다.
